SILO-CHUTE.

Application led November 10, 1915.

To all whom it may concern Be it known that I, CHARLES S. BROWN,residing .at Rice, in the county of Stevens and State of Washington,have invented a new and Improved Silo-Chute, of which the following is aspecification.

My present invention, which relates to improvements in silos, is moreparticularly in the nature of an improved chute co-iistruction, adaptedfor being used with the ordinary types of silos having outwardly openingdoors arranged in vertical series, and my said invention primarily hasfor its object to provide an improved construction that includes aframing built up along the front or doorside of the silo, a chute formedof sections, one section for each door of the silo, and means foradjusting the said sections successively, up or down, and in such amanner that the operation of the silage is expeditiously accomplished. i

Another object of my invention is to provide an improved means fordischarging the silage from the silo, in which is included a suitableframing built up along the front or door side of the silo, and composedof a series of vertically arrangedy hinged members that form platformsfor their respective adjacent silo doors, means for gaining access tothe said platforms, and a chute formed of hinged sections, one sectionfor each platform and silo door, and adapted for being readily andsuccessively adjusted to the discharging positions by the operatorstanding on the platform and other means for sustaining the chutesections in their several adjusted positions.

With other objects in view that will hercinafter appear my presentinvention embodies'the peculiar construction and novel arrangement ofthe parts hereinafter fully explained, specifically pointed out in theclaims and illustrated in the accompanying drawing, in which Figure 1 isa vertical section of aportion of a silo with my improved constructionof chute (shown in side elevation) operatively combined therewith, oneof the chute sec tions being shown positioned for receiving the silagedischarging from the silo. Fig. 2 is ay horizontal section .taken on theline 2 2 on Fig. l. Fig. 3 is a detail view on a slightly enlarged scaletaken on the line 3 3 on Fig. 1. Figs. 4 and 5 are detail sections ofslightly modified forms of my invention hereinafter specificallymentioned.

serial No. 60,757.

In the drawings, in which like numerals indicate like parts in all ofthe figures, 1 designa-tes that p ortion of the wall` of a silo, havinglthe series of door openings 2, in vertical alinenient, and doors20 that are hinged to swing outwardly.

Built vertically along the door side of the each door opening 2, andmade fast by angle plates 30 to the sills 21 of the door, one sevJ ofsuch angle iron connections being clearly shown in Fig. 2 of thedrawings. The said framing also includes closed sides formed of boards 4nailed to the joists 3 and a series of platforms in the nature of vdropdoors 5 hinged at one end to the upper edge of one sill and adapted,when lowered to rest on the opposite sill, the lowered position rof oneof the said platform doors being shown in Fig. l. When at the upposition the door 5 is held by a catch 50 see Fig. l.

For readily gaining access to any of the platforms, ladder rungs 6 aresecured to the door sills and to the doors, it being understoodV thatafter reaching an upper platform or landing the operator lowers the doorfor the platform below'and so on.

So far as described, it will be noticed that the framing built up infront of the silo is in the nature of a vertically extended housing orchamber, and at this point it should be stated, the front wall of saidchamber is in the nature of a vertically extended metallic chute, formedin sections, one of such sections being provided for each doorway forthe silo.

The chute construction, in the preferred form, as is best shown in Figs.1 and 2, includes a substantially semicircular outer metal-wall 7 thatextends the full length of the framing and includes fiat side extensionsthe ends of which are bent at right angles to form angle plates 71 forextending over the adjacent outer edges of the said boards 4-4 (seeFigs. 2 and 3). At suitable intervals and in vertical series, one foreach silo doorway, the wall 7 has a substan` tially semi-circularspacing member 8 in the nature of `a metal band the ends o-f which formside portions that engage and are riveted to the fiat side extensions 70 of the member 7 and whose extremities are turned inwardly to formangle ianges 81, which extend over the outer adjacent edges of the Siiboard sides to which they are made fast by bolts 82, that also securethe ang-led plates 71 of the member 7 which latter are bulged to lap theflanges 81, as is clearly shown inV Fig. 3. rlhe chute construction alsoincludes..V

a series of hinged members thatform haltl portions of the completelchute when they are swung up to a closed position' as shown at X, Fig.1,:and serve as chute or conveyer members when they are dropped down tothe position Y in Figs. 1 land 2.".Each member 73 has its lower endconnected to the upper VVend ofthe next chutelsection or member 73 by ahinged joint 7 4 and the said lower end is of partial elbow shape' asat74:, to form a substantial closure at the opposite edges when the said`hing"ed chute or .trough is at the fsaid'down position, the said loweredge belthe upper end 7 3a of the member y73 and the ring 8,'the latterhas an oiset asat 74a to v:Eorm a seat Jfor the said upper end 7 3,which in practice has a suitable catch 7 Bb'for hold- 'pendent positionsby chains 11.

ing 'it to its locked position.

' 11n the preferred structure, the chute .er

trough-like sections are sustained at their By reason of the peculiarconstruction and .arrangementv of the parts so far describedandillustrated in Figs. 1', 2 and 3 of the drawings, a simple and easilyadjusted means for discharging the silo is provided.

In filling the silo, the same is done pneumatically by applying a blowertothe lower end of the chute and by a U tube connection on the upper endof the chute that discharges into the top of the silo, as shown in myPatent No. 1,145,550 for silo door system, dated July 6, 1915.

InV discharging the silo, the uppermost hinged section of the chute isswung down into the uppermost doorway of the silo and the silage israked out and` discharged through a large chute member 73 from whence itpasses into the closed chute through which it drops to the ground into asuitable wagon or other receptacle, it being also understood that'thechute sections 73 are successively lowered from the top j to Vthe'bottomof the chute'when,y discharging the silo. j y

1n Fig. l is illustrated a vsomewhat modifiedfarrangement ofmy'invention and in this form the chute,v instead of being formed withhinged sections, las in the pre- A erred form, has, at each doorway ofthe silo, a lateral discharging mouth C, that is normally closed by adrop ycover plate D,

which in practice may have a spring latch to hold it closed.

When using a chute, as shown in Fig.' 4,

a long` funnel C is employedfor connecting the mouth` C with the silo,the discharging end of Such funnel extending over the door sill of the,silo as shown.

In Fig. 5 is shown a further modification of my'invention and in thisform the hinged chute section is also used, and it `diii'ers from thechute section 73 in the preferred form, in that it is long enough toextend intlo the silo doorway and' rest on the door sil j From the'foregoing .description taken `in connection with the drawings thecomplete operation, the manner in which my invention is utilized and theadvantages thereof will be readily apparent to those skilled in the artto which it relates.
